Product details
Overview
S29GL032N90BFI043 from Infineon Technologies (formerly Cypress) is a 32 Mbit (4,194,304-byte), 16-bit-wide single-power-supply MirrorBit Flash memory with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed 128-word electronic serial number. It operates from 2.7–3.6 V VCC and 1.65–3.6 V VIO, supports JEDEC-compliant command set, and is used in industrial control firmware storage where secure boot code retention and field-upgradable firmware are required.
For engineers reviewing the S29GL032N90BFI043 datasheet, S29GL032N90BFI043 pinout, S29GL032N90BFI043 application, or S29GL032N90BFI043 equivalent, key selection criteria include uniform 64 KB sector erase granularity, hardware write protection via WP#/ACC, CFI compliance for host auto-configuration, and 100,000 erase cycles per sector with 20-year data retention.
Technical Context
This device implements a command-based, nonvolatile flash memory architecture using hot-electron injection for programming and hot-hole assisted erase. It features dual voltage domains (VCC for core logic, VIO for I/O level setting), enabling interoperability with 1.8 V or 3.3 V host buses without level shifters.
The internal state machine handles all erase and program operations autonomously after command initiation; status is reported via DQ7 polling, DQ6 toggle bits, or RY/BY# output. Sector protection includes persistent lock bits and password-controlled access to designated sectors, with Secured Silicon Sector permanently locked post-factory programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 32 Mbit (4,194,304 bytes), organized as 2,097,152 × 16-bit words |
| Access time | 90 ns at VCC = 2.7–3.6 V and VIO = 2.7–3.6 V - enables direct interface with legacy 10 MHz microcontrollers |
| Sector architecture | 64 uniform 64 KB sectors - simplifies firmware partitioning and OTA update management |
| Erase endurance | 100,000 cycles per sector - supports frequent field firmware updates in industrial gateways |
| Data retention | 20 years at 125 °C - meets extended lifetime requirements for automotive and telecom infrastructure |
| Supply voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V - allows flexible I/O voltage selection independent of core supply |
| Page read buffer | 8-word (16-byte) page read buffer - reduces sequential read latency in boot code execution |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body). Pinout validated per Cypress/Infineon datasheet 001-98525 Rev. *B, Figure 1 (S29GL032N Models 03/04).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 4 MB addressing space; A-1 used as DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; DQ15 doubles as A-1 for byte/word mode selection when BYTE# asserted |
| CE# | Chip enable | Active-low chip select; device enters standby when CE# high, reducing current to 1 µA |
| OE# | Output enable | Controls data bus drivers during read; decouples read timing from CE# assertion |
| WE# | Write enable | Initiates command latching or data programming; must be strobed with valid address/data |
| WP#/ACC | Write protect / accelerate input | Low = hardware sector protection; high + elevated voltage = accelerated programming for production throughput |
| RY/BY# | Ready/Busy output | Open-drain active-low signal indicating ongoing erase/program operation completion |
| RESET# | Hardware reset | Aborts current operation and returns device to read mode; synchronizes with system power-on reset |
| BYTE# | Bus width select | Low = x16 mode (DQ0–DQ15 active); high = x8 mode (DQ0–DQ7 only, DQ8–DQ15 tri-stated) |
| VIO | I/O voltage reference | Sets input threshold and output swing - enables mixed-voltage system interfacing without external translators |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-programmed, permanently locked region containing unique 8-word electronic serial number - enables secure device identity binding in firmware authentication |
| Advanced Sector Protection | Persistent lock bits and 16-byte password protection per sector - prevents unauthorized firmware modification in deployed edge devices |
| Program/Erase Suspend | Allows host to pause active programming or erasing to service interrupts or read other sectors - essential for real-time OS boot loaders |
| CFI compliance | Standardized query structure at address 0x55 for automatic detection of geometry, timings, and protection features - eliminates hard-coded flash parameters in bootloader |
| Unlock Bypass mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts firmware update time by ~50% in high-volume manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI040 | Same die, 48-ball fine-pitch BGA (VBK048) package instead of 48-pin TSOP; identical electrical specs and command set | Requires PCB redesign for BGA layout and reflow profile; better thermal performance and smaller footprint | Select for space-constrained designs where board area and thermal dissipation outweigh assembly complexity |
| MX29GL320EBTI-90G | 32 Mbit, 90 ns, but uses Macronix's MX29GL architecture; lacks Secured Silicon Sector and CFI compliance; different command set | Not drop-in compatible; requires bootloader firmware rewrite and validation for erase/write sequences | Select only when cost sensitivity outweighs security and interoperability requirements, and full firmware requalification is feasible |
Compared with S29GL032N90BFI043, the TSOP-packaged alternative offers identical functionality in a through-hole-compatible form factor, while the Macronix part sacrifices security and standards compliance for lower unit cost-making it suitable only for non-secure, cost-driven consumer applications.

FAQ
Is S29GL032N90BFI043 pin-compatible with earlier S29GL032N variants?
Yes - S29GL032N90BFI043 uses the 48-pin TSOP package (TS048) and maintains identical pinout, voltage ratings, and command set as all S29GL032N devices with 'B' speed grade and 'I' industrial temperature range. No PCB or firmware changes are required for replacement within the same speed/temperature family.
Does this device support both x8 and x16 data bus modes?
Yes - the BYTE# input selects bus width: asserted low enables full 16-bit DQ0–DQ15 operation; asserted high configures x8 mode with DQ0–DQ7 active and DQ8–DQ15 high-impedance. This allows flexible integration with 8-bit microcontrollers or 16-bit processors without external multiplexing.
What is the function of the WP#/ACC pin beyond write protection?
WP#/ACC serves dual roles: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with elevated voltage (typically 5.5 V), it activates accelerated programming mode, reducing individual word programming time by ~30% for high-throughput manufacturing.
Can the Secured Silicon Sector be reprogrammed after factory locking?
No - the Secured Silicon Sector is permanently locked at the factory or by customer command sequence. Once the lock bit is set, no further writes or erases are possible in that 256-byte region. The 8-word electronic serial number is pre-programmed and immutable, ensuring device-level uniqueness for secure boot and anti-counterfeiting.
